如何通过momentjs检查过去的随机日期是否至少为一天（24小时）？

类似的东西：

const today = moment()
const isAtLeastADayAgo = today.subtract(dateToCheck) > 1 // ??

Answer 1

您只需使用isBefore

即可

＆＃13;

function isADayAgo(input){
  let yesterday = moment().subtract(1, 'd');
  return input.isBefore(yesterday);
}

const isAtLeastADayAgo = isADayAgo(moment());
console.log(isAtLeastADayAgo);

＆＃13;

<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>

＆＃13;

或者您可以将diff限制粒度用于日期：

＆＃13;

const today = moment();
const dateToCheck = moment().subtract(3, 'd');
const isAtLeastADayAgo = today.diff(dateToCheck, 'd') > 1;
console.log(isAtLeastADayAgo);

＆＃13;

<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>

＆＃13;

Answer 2

我建议你使用普通的javascript Date构造函数。

var today =  new Date();
var pastDate = // some past date
// 86400 seconds in 24hrs
// getTime() will return you date in milliseconds
if(86400000 < today.getTime()-pastDate.getTime()) will return true if past date is older than 24Hrs.

Answer 3

const isAtLeastADayAgo = moment().subtract(1,'days')>dateToCheck
